Likewise, violet vestments are worn, except on feasts, from Septuagesima Sunday until Holy Thursday. As during Advent and Lent, the Gloria and Te Deum are no longer said on Sundays. The readings at Matins for this week are the first few chapters of Genesis, telling of the creation of the world, of Adam and Eve, the fall of man and resulting expulsion from the Garden of Eden, and the story of Cain and Abel.
In the following weeks before and during Lent, the readings continue to Noah, Abraham, Isaac, Jacob, and Moses. The Gospel reading for Septuagesima week is the parable of the Workers in the Vineyard (Matthew 20:1-16)
